Abstract

Aspects of a method and system for a programmable interference suppression module may include receiving a communication signal comprising one or more desired signal, and one or more undesired signals. The communication signal may be utilized to generate estimated channel state information. The estimated channel state information may be formatted for use in interference suppression. A reduced interference signal may be generated from a delayed version of said communications signal and the estimated channel state information, wherein the one or more undesired signals may be attenuated. The reduced interference signal may be formatted for post-processing. The desired signals may comprise WCDMA and/or HSDPA signals, and the undesired signals may be inter-cell and/or intra-cell interference. Further processing may comprise HSDPA processing and/or RAKE finger processing. The communication signal may be a Universal Mobile Telecommunication System (UMTS) compliant signal.

Claims (32)

1. A method for signal processing, the method comprising:

performing by one or more circuits in a wireless communication device:

receiving a communications signal comprising one or more desired signal, and one or more undesired signals;

generating, from said communications signal, estimated channel state information;

formatting said estimated channel state information for use in interference suppression;

generating a reduced interference signal from a delayed version of said communications signal and said estimated channel state information, wherein said one or more undesired signals are attenuated; and

formatting said reduced interference signal for post-processing.

2. The method according to claim 1 , wherein said desired signals comprise WCDMA and/or HSDPA signals.

3. The method according to claim 1 , wherein said undesired signals are inter-cell and/or intra-cell interference.

4. The method according to claim 1 , wherein said further processing is HSDPA processing and/or RAKE finger processing.

5. The method according to claim 1 , wherein said communications signal is a signal conforming to the Universal Mobile Telecommunication System (UMTS) standard.

6. The method according to claim 1 , wherein said estimated channel state information comprises RAKE finger position estimates and channel coefficient estimates.

7. The method according to claim 1 , wherein said one or more circuits comprise an interference cancellation preprocessor, and said one or more circuits enable formatting of said estimated channel state information by said interference cancellation preprocessor.

8. The method according to claim 1 , wherein said one or more circuits comprise an interference cancellation core processor, and said one or more circuits enable generating of said reduced interference signal by said interference cancellation core processor.

9. The method according to claim 8 , wherein said interference cancellation core processor comprises an interference cancellation engine.

10. The method according to claim 1 , wherein said one or more circuits comprise an interference cancellation postprocessor, and said one or more circuits enable formatting of said reduced interference signal for said further processing by interference cancellation postprocessor.

11. A system for signal processing, the system comprising:

one or more circuits for use in a wireless communication device, wherein said one or more circuits are operable to:

receive a communication signals comprising one or more desired signal, and one or more undesired signals;

generate, from said communications signal, estimated channel state information;

format said estimated channel state information for use in interference suppression;

generate a reduced interference signal from a delayed version of said communications signal and said estimated channel state information, wherein said one or more undesired signals are attenuated; and

format said reduced interference signal for post-processing.

12. The system according to claim 11 , wherein said desired signals comprise WCDMA and/or HSDPA signals.

13. The system according to claim 11 , wherein said undesired signals are inter-cell and/or intra-cell interference.

14. The system according to claim 11 , wherein said further processing is HSDPA processing and/or RAKE finger processing.

15. The system according to claim 11 , wherein said communications signal is a signal conforming to the Universal Mobile Telecommunication System (UMTS) standard.

16. The system according to claim 11 , wherein said estimated channel state information comprises RAKE finger position estimates and channel coefficient estimates.

17. The system according to claim 11 , wherein said one or more circuits comprise an interference cancellation preprocessor, and said one or more circuits are operable to format said estimated channel state information utilizing said interference cancellation preprocessor.

18. The system according to claim 11 , wherein said one or more circuits comprise an interference cancellation core processor, and said one or more circuits are operable to generate said reduced interference signal utilizing said interference cancellation core processor.

19. The system according to claim 18 , wherein said interference cancellation core processor comprises an interference cancellation engine.

20. The system according to claim 11 , wherein said one or more circuits comprise an interference cancellation postprocessor, and said one or more circuits are operable to format said reduced interference signal for said further processing utilizing said interference cancellation postprocessor.
